snapshot solution: Existing snapshots that were taken after this one will be erased.

Hi Team, when I want to commit the older snapshots I'm getting warning stating " Existing snapshots that were taken after this one will be erased.". is there any way we can retain the latest snapshots as is in the chain? I knew cloning and template export options are there to secure that latest snapshot data but these are will consume additional space in storage and take time.

Restart oVirt-Engine
by Jeremey Wise 09 Jan '25

09 Jan '25

How ,without reboot of hosting system, do I restart the oVirt engine? # I tried below but do not seem to effect the virtual machine [root@thor iso]# systemctl restart ov ovirt-ha-agent.service ovirt-imageio.service ovn-controller.service ovs-delete-transient-ports.service ovirt-ha-broker.service ovirt-vmconsole-host-sshd.service ovsdb-server.service ovs-vswitchd.service [root@thor iso]# # You cannot restart the VM " HostedEngine " as it responses: Error while executing action: HostedEngine: - Cannot restart VM. This VM is not managed by the engine. Reason is I had to do some work on a node. Reboot it.. it is back up.. network is all fine.. Cockpit working fine... and gluster fine.. But oVirt-Engine refuses to accept the node is up. -- p <jeremey.wise(a)gmail.com>enguinpages

Unable to access ovirt Admin Screen from ovirt Host
by louisb＠ameritech.net 08 Dec '24

08 Dec '24

I've reinstalled ovirt 4.4 on my server remotely via cockpit terminal. I'm able to access the ovirt admin screen remotely from the laptop that I used for the install. However, using the same URL I'm unable to gain access to the admin screen. Following the instruction in the documentation I've modified the file: /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf, to reflect the DNS name and I enter in the IP address. But I'm still unable to access the screen from the server console. What else needs to change in order to gain access from the server console? Thanks

SPM and Task error ...
by Enrico 22 Nov '24

22 Nov '24

Hi all, my ovirt cluster has got 3 Hypervisors runnig Centos 7.5.1804 vdsm is 4.20.39.1-1.el7, ovirt engine is 4.2.4.5-1.el7, the storage systems are HP MSA P2000 and 2050 (fibre channel). I need to stop one of the hypervisors for maintenance but this system is the storage pool manager. For this reason I decided to manually activate SPM in one of the other nodes but this operation is not successful. In the ovirt engine (engine.log) the error is this: 2019-07-25 12:39:16,744+02 INFO [org.ovirt.engine.core.bll.storage.pool.ForceSelectSPMCommand] (default task-30) [7c374384-f884-4dc9-87d0-7af27dce706b] Running command: ForceSelectSPMCommand internal: false.

oVirt networks
by Enrico Becchetti 28 Aug '24

28 Aug '24

Dear all, Ineed your help to understand how to configure the network of a new oVirt cluster. Mynew system will have a 4.3 engine thatruns in a virtual machine, andsome Dell R7525 AMD EPYC hypervisors, eachholding two 4-port PCI network cards. These servers will have node-ovirt image again in version 4.3. As for the network, there are two HPE Aruba 2540G, non-stackable, with 24 1Gbs ports and 2 10Gbs uplinks to the star center. This is a simplified scheme: My goal is to make the most of the server's 8 ethernet interfaces to have both reliability and maximum possible throughput. This cluster will have two virtual networks, one forovirt management and one for the traffic of individual virtual machines. With that said here's what my idea is. I would like to have two links aggregated by 4Gbs, one for ovrtmgt and the other for vmnet. With the ovirt web interface I can createan active-passive "Mode 1" bond, but this won'tallow me to go beyond 1Gbs. Alternatively I could create a "Mode 4" bond 802.3ad but unfortunately the switches are not stacked and therefore not even this solution applies. This is an example with active passive configuration: Can you tell me if ovirt can generate//nested bonds? Or do you have other solutions ? Thanks a lot !

But when I try to boot the vm I obtain this error: booting from dvd/cd... boot failed: could not read from cdrom (code 0005) no bootable device The iso file has been uploaded with success in the data storage domain and so the vm lets my attach the iso to the vm in the boot settings. Can you help me? Thank you

How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?
by Derek Atkins 28 Jun '24

28 Jun '24

Hi, I've got a single-host hosted-engine deployment that I originally installed with 4.0 and have upgraded over the years to 4.3.10. I and some of my users have upgraded remote-viewer and now I get an error when I try to view the console of my VMs: (remote-viewer:8252): Spice-WARNING **: 11:30:41.806: ../subprojects/spice-common/common/ssl_verify.c:477:openssl_verify: Error in server certificate verification: CA signature digest algorithm too weak (num=68:depth0:/O=<My Org Name>/CN=<Host's Name>) I am 99.99% sure this is because the old certs use SHA1. I reran engine-setup on the engine and it asked me if I wanted to renew the PKI, and I answered yes. This replaced many[1] of the certificates in /etc/pki/ovirt-engine/certs on the engine, but it did not update the Host's certificate. All the documentation I've seen says that to refresh this certificate I need to put the host into maintenance mode and then re-enroll.. However I cannot do that, because this is a single-host system so I cannot put the host in local mode -- there is no place to migrate the VMs (let alone the Engine VM). So.... Is there a command-line way to re-enroll manually and update the host certs? Or some other way to get all the leftover certs renewed? Thanks, -derek [1] Not only did it not update the Host's cert, it did not update any of the vmconsole-proxy certs, nor the certs in /etc/pki/ovirt-vmconsole/, and obviously nothing in /etc/pki/ on the host itself. -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net 23 Apr '24

23 Apr '24

We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS. Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000] Mar 1 11:49:06 srvXX abrt-hook-ccpp: invalid number 'iothread1' Mar 1 11:49:11 srvXX libvirtd: 2019-03-01 00:49:11.116+0000: 13365: error : qemuMonitorIORead:609 : Unable to read from monitor: Connection reset by peer Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off. Cheers.

Cannot restart ovirt after massive failure.
by Gilboa Davara 18 Jan '24

18 Jan '24

Hello all, During the night, one of my (smaller) setups, a single node self hosted engine (localhost NFS) crashed due to what-looks-like a massive disk failure (Software RAID6, with 10 drives + spare). After a reboot, I let the RAID resync with a fresh drive) and went on to start oVirt. However, no such luck. Two issues: 1. ovirt-ha-broker fails due to broken hosted engine state (log attached). 2. ovirt-ha-agent fails due to network test (tcp) even though both remote-host and DNS servers are active. (log attached). Two questions: 1. Can I somehow force the agent to disable the network liveliness test? 2. Can I somehow force the broker to rebuild / fix the hosted engine state? - Gilboa
